PRODUCT IDENTIFICATION

Table 32 provides a summary of the registers that identify

the product: PROD_ID, which identifies the product type;

LOT_ID1 and LOT_ID2, the 32-bit lot identification code;

and SERIAL_NUM, which displays the 16-bit serial number.

All four registers are two bytes in length.
